InNexus Inc. Announces A Scientific Discovery And Expansion Of Its SuperAntibody Intellectual Property

10/19/2005 5:10:46 PM

VANCOUVER, British Columbia--(BUSINESS WIRE)--Nov. 14, 2003--InNexus Biotechnology, Inc. (the "Company") announced today the scientific discovery that its SuperAntibodies can form an association (one antibody with the other, referred to as "dimerization") and that this appears to be related to their high potency in disease treatment. This discovery has enabled InNexus to file an additional patent that protects more uses of SuperAntibody Technology ("SAT") and will ultimately allow InNexus to work with more corporate partners. This discovery, recently published by InNexus's collaborators, Immpheron, Inc. of Lexington, Kentucky, has shown that monoclonal antibodies can be conjugated through carbohydrate linkage to a peptide capable of conferring a dimerizing ability to antibodies. The specific studies utilized antibodies to the B-cell receptor, present on normal and malignant B-cells, and demonstrated that such modified antibodies were superior at inducing apoptosis ("cell suicide") and in growth inhibition as well as binding better than an unmodified, native antibody - all key properties of therapeutically active antibodies.

The peer-reviewed publication referenced herein has been published and is posted on InNexus's website ( The citation is: "Enhanced Tumor Targeting and Apoptosis Using Non-Covalent Antibody Homodimers," Y Zhao and H Kohler. J. Immunotherapy 25(5) :396-404, 2002.

Dr. Charles Morgan, President of InNexus commented, "This key scientific discovery is important for allowing InNexus to file for additional patent protection that enhances the intellectual property base for SAT. It will also enable SAT to appeal to more potential corporate partners and allow InNexus to develop antibodies for the treatment of additional forms of cancer and other life-threatening diseases."

InNexus has recently entered into an agreement with Corixa Corp (NASDAQ:CRXA - News) to use SAT with up to four of their antibodies currently in development.
